toplevel config.log

I'm attaching the toplevel config.log.  From it I read that the compiler is
configure:4103: gcc --version >&5
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658)
(LLVM build 2336.1.00)

The configure command was
  ../configure --enable-languages=c,c++,fortran
(my build directory is a subdirectory of the gcc directory)
